This 4-pack of heavy-duty U-bolts by AB Tools is designed for mechanics, trailer builders, and DIY enthusiasts needing secure, reliable fastening for frames and heavy-load applications. Featuring high-tensile strength and a corrosion-resistant gold finish, this kit provides a complete hardware solution for structural assembly, though users must verify the 50mm internal width matches their specific mounting requirements before purchase.

These bolts feature a standard 10mm (M10) diameter thread.
The gold-plated finish offers good corrosion resistance, but for constant saltwater submersion, stainless steel hardware is generally recommended.
Yes, the kit includes 4 backing plates, 4 U-bolts, washers, and nyloc nuts.
The backing plates are 6mm thick to provide enhanced load distribution and durability.
It is generally advised to replace nyloc nuts if they have been removed, as the nylon locking mechanism loses its effectiveness after multiple uses.
The total internal length of the U-bolt is 130mm.
Ensure the threads are free of debris or paint buildup. Apply a small amount of lubricant to the thread if resistance persists.
Double-check that the frame width does not exceed 50mm; if the frame is wider, this specific size is incompatible.
Verify that the bolt has been tightened to the appropriate torque specification; nyloc nuts should only be reused if the nylon insert still shows visible resistance when threading.
Installation Steps:
Compatibility: These bolts feature an M10 thread. Verify that your existing brackets are drilled for 10mm hardware.
Care: Periodically inspect the hardware for signs of stress or movement. While the gold plating is corrosion-resistant, applying a light coat of anti-seize or silicone-based lubricant to the threads during installation can prevent galvanic corrosion and make future adjustments significantly easier.
